Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically to a pipeline cleaning device. Background Technology

[0002] Ventilation ducts are mostly hollow, round pipes. After a period of use, dust and other impurities will accumulate on their inner walls. These impurities, accumulating over time, can affect both the air quality and the flow of air within the duct. Therefore, it is necessary to clean the inner walls of the ventilation ducts regularly to remove these accumulated impurities.

[0003] Existing cleaning methods include manual cleaning and mechanical cleaning. Manual cleaning is not only labor-intensive but also inefficient. Mechanical cleaning is particularly convenient when the pipes are long. For example, patent document CN222659550U discloses an automatic pipe cleaning device. This device uses a support motor to drive rollers on a support rod to support the device inside the pipe. Simultaneously, the cleaning motor and drive motor are activated, causing the cleaning device to advance within the pipe while the cleaning motor drives the cleaning brushes to clean the pipe.

[0004] The aforementioned cleaning device uses a cleaning brush to clean the inner wall of the pipe. However, after the cleaning brush sweeps the dust off the inner wall of the pipe, the dust will fall into the pipe. Subsequently, an air blowing device is needed to blow away the dust in the pipe, which adds an extra cleaning process and affects the cleaning efficiency. Summary of the Invention

[0005] In view of this, the present invention provides a pipe cleaning device to solve the technical problem that dust after cleaning the pipes in the prior art will fall into the pipes, thus affecting the cleaning efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a pipe cleaning device, including a rotating shaft and a drive motor for driving the rotating shaft to rotate. A threaded disc is rotatably connected to the rotating shaft. A limiting disc fixedly connected to the rotating shaft is provided on one side of the threaded disc. Multiple threaded sliders are installed on the threaded disc. A blade is installed on one end of the threaded slider away from the rotating shaft. Brush bristles are installed at the end of the blade.

[0007] The limiting disc has multiple limiting grooves in its radial direction, the threaded slider is located in the limiting groove, and a locking bolt is provided between the threaded disc and the rotating shaft.

[0008] By adopting the above technical solution, during use, first remove the locking bolt, allowing the threaded disc and the rotating shaft to rotate relative to each other. Rotating the threaded disc causes the threaded slider to move radially along the disc due to the limiting groove on the limiting disc. When the bristles contact the inner wall of the pipe, stop rotating the threaded disc and install the locking bolt to lock the threaded disc and the rotating shaft. The drive motor then rotates the rotating shaft, which in turn rotates the threaded disc and the blades. The bristles on the blades clean the inner wall of the pipe, while simultaneously blowing away the swept dust, reducing the amount of dust falling into the pipe and improving cleaning efficiency.

[0009] Furthermore, a support frame is rotatably connected to the rotating shaft, and multiple movable frames are provided on the support frame, with support rollers installed on the movable frames.

[0010] By adopting the above technical solution, the support roller can abut against the inner wall of the pipe, which helps to increase the stability of the cleaning device during the cleaning process of the pipe.

[0011] Furthermore, an adjusting cylinder is connected to the threaded disc, a cone is sleeved on the rotating shaft, a threaded cylinder is connected to the cone, the threaded cylinder is connected to the rotating shaft by a key, and the adjusting cylinder is connected to the threaded cylinder by a thread.

[0012] The movable frame includes a V-shaped rod and a guide rod connected to one end of the V-shaped rod. The side wall of the truncated cone is provided with a guide groove. The guide rod is slidably connected to the guide groove. The other end of the V-shaped rod is slidably connected to the support frame.

[0013] By adopting the above technical solution, before cleaning, rotating the adjusting cylinder drives the threaded disc to rotate synchronously, causing the threaded slider to drive the blades to move radially along the threaded disc. Simultaneously, because the adjusting cylinder and the threaded cylinder are connected by threads, and the threaded cylinder and the rotating shaft are slidably connected, the rotating shaft remains stationary. As the adjusting cylinder rotates, it drives the threaded cylinder and the cone to move axially along the rotating shaft. Since the V-shaped rod, the cone, and the support frame are all slidably connected, the cone pushes the V-shaped rod to move radially along the rotating shaft, causing the support rollers to abut against the inner wall of the pipe, thus enabling the support rollers to support pipes of different inner diameters. Because the blades can drive the bristles to move radially along the threaded disc, they can also clean pipes of different inner diameters.

[0014] Furthermore, the support frame is provided with a limiting frame, and the part of the V-shaped rod that connects to the guide rod passes through the limiting frame.

[0015] By adopting the above technical solution, the limiting frame and the cone work together to limit the travel of the V-shaped rod, which helps to keep the V-shaped rod, the cone, and the support frame in a state where they can slide relative to each other.

[0016] Furthermore, the support frame is provided with a radial groove, the end of the V-shaped rod is slidably disposed in the groove, and a return spring is connected between the groove and the V-shaped rod.

[0017] By adopting the above technical solution, when the V-shaped rod moves away from the axis of rotation, the return spring is stretched; when the V-shaped rod moves closer to the axis of rotation, the return spring is contracted. After the pipe cleaning is completed, the cleaning device is removed from the pipe, and the adjusting cylinder is rotated in the opposite direction. Under the action of the return spring, the V-shaped rod is reset.

[0018] Furthermore, a connector is detachably connected to one end of the blade away from the threaded slider, and the bristles are fixedly mounted on the connector.

[0019] By adopting the above technical solution, the bristles can be detached from the blades, making it easier to clean the bristles and improving the cleanliness of the bristles cleaning the inner wall of the pipe.

[0020] Furthermore, the drive motor is installed inside the housing, and the rotating shaft is rotatably connected to the housing.

[0021] By adopting the above technical solution, the housing can reduce dust falling onto the drive motor. At the same time, it is beneficial to apply external driving force to the housing, thereby enabling the cleaning device to move inside the pipe and clean the pipe.

[0022] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0023] 1. The drive motor of this utility model drives the brush bristles and blades to rotate synchronously. While the brush bristles clean the inner wall of the pipe, the blades can blow away the dust that has been swept up, reducing the amount of dust falling into the pipe and improving cleaning efficiency.

[0024] 2. The supporting roller of this utility model can abut against the inner wall of the pipe, which helps to increase the stability of the cleaning device during the cleaning process of the pipe. The supporting roller and the bristles can move synchronously along the radial direction of the rotating shaft, which can be used to clean the inner wall of pipes of different diameters.

[0025] 3. The bristles of this utility model can be detached from the blades, which facilitates cleaning of the bristles and helps to improve the cleanliness of the bristles cleaning the inner wall of the pipe. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the embodiments of this utility model. Figures 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0034] Example

[0035] This embodiment provides a pipe cleaning device, such as Figure 1 and Figure 2 As shown, the device includes a housing 1, with a rotating shaft 3 rotatably connected inside the housing 1, one end of which extends outside the housing 1. A drive motor 2, which drives the rotating shaft 3 to rotate, is installed inside the housing 1.

[0036] like Figure 1 As shown, an adjusting cylinder 41 is sleeved on the rotating shaft 3, and a threaded disc 4 is connected to the end of the adjusting cylinder 41. The threaded disc 4 and the rotating shaft 3 are rotatably connected. A limiting disc 5 is provided on the side of the threaded disc 4 away from the adjusting cylinder 41, and the limiting disc 5 is fixedly connected to the rotating shaft 3. The axes of the rotating shaft 3, the adjusting cylinder 41, the threaded disc 4, and the limiting disc 5 are collinear.

[0037] like Figure 2 and Figure 3As shown, a locking bolt 46 is installed between the adjusting cylinder 41 and the rotating shaft 3. Tightening the locking bolt 46 allows the rotating shaft 3 and the adjusting cylinder 41 to rotate synchronously. Loosening the locking bolt 46 allows the rotating shaft 3 and the adjusting cylinder 41 to rotate relative to each other.

[0038] like Figure 3 and Figure 4 As shown, a plurality of threaded sliders 42 are provided on one end of the threaded disc 4 near the limiting disc 5. The plurality of threaded sliders 42 are distributed radially along the threaded disc 4, and the side of the threaded slider 42 that contacts the threaded disc 4 is also provided with threads.

[0039] like Figure 4 and Figure 5 As shown, a plurality of limiting grooves 51 are provided on the limiting disk 5 near the threaded disk 4, and the plurality of limiting grooves 51 are distributed radially along the limiting disk 5. In this embodiment, there are six limiting grooves 51 and six threaded sliders 42, and a threaded slider 42 slides in each limiting groove 51.

[0040] like Figure 4 As shown, a blade 43 is mounted on the end of the threaded slider 42 away from the rotating shaft 3. A connector 44 is bolted to the end of the blade 43 away from the threaded slider 42. Brush bristles 45 are mounted on the connector 44. The connector 44 has a plate-like structure.

[0041] like Figure 2 and Figure 3 As shown, removing the locking bolt 46 allows the adjusting cylinder 41 and the rotating shaft 3 to rotate relative to each other. Rotating the adjusting cylinder 41 causes the threaded disc 4 to rotate synchronously. Figure 5 As shown, due to the limiting groove 51 on the limiting plate 5 limiting the threaded slider 42, the threaded slider 42 drives the blade 43 to move radially along the threaded plate 4. When the brush bristles 45 contact the inner wall of the pipe, the threaded plate 4 stops rotating and the upper locking bolt 46 is tightened to lock the adjusting cylinder 41 and the rotating shaft 3.

[0042] like Figure 2 and Figure 3 As shown, the drive motor 2 drives the rotating shaft 3 to rotate, which in turn drives the adjusting cylinder 41, the threaded disc 4 and the blade 43 to rotate. The bristles 45 on the blade 43 clean the inner wall of the pipe. At the same time, the blade 43 blows away the dust that has been swept down, reducing the amount of dust falling into the pipe and improving cleaning efficiency.

[0043] like Figure 1 As shown, a support frame 6 is rotatably connected to the part of the rotating shaft 3 located between the housing 1 and the adjusting cylinder 41, and three movable frames 7 are slidably provided on the support frame 6.

[0044] like Figure 1As shown, a frustum 8 is fitted onto the rotating shaft 3 between the adjusting cylinder 41 and the support frame 6. A threaded cylinder 9 is connected to one end of the frustum 8 near the adjusting cylinder 41. The axes of the frustum 8, the threaded cylinder 9, and the rotating shaft 3 are collinear.

[0045] like Figure 1 As shown, the threaded cylinder 9 is connected to the rotating shaft 3 by a key, and the threaded cylinder 9 is connected to the adjusting cylinder 41 by a thread. The outer side of the threaded cylinder 9 is provided with an external thread, and the inner wall of the adjusting cylinder 41 is provided with an internal thread that matches the external thread.

[0046] like Figure 1 As shown, the movable frame 7 includes a V-shaped rod 71 and a guide rod 72 vertically connected to one end of the V-shaped rod 71. Figure 6 As shown, the side wall of the truncated cone 8 has three guide grooves 81, and three guide rods 72 are slidably connected in the three guide grooves 81. The guide grooves 81 are dovetail grooves, and dovetail blocks are provided on the corresponding guide rods 72. The support frame 6 has three sliding grooves 62 in the radial direction, and the other end of the V-shaped rod 71 is slidably connected in the sliding groove 62. A return spring 63 is connected between the other end of the V-shaped rod 71 and the sliding groove 62.

[0047] like Figure 1 and Figure 6 As shown, the support frame 6 has three limiting frames 61 at one end near the truncated cone 8, and the part of the V-shaped rod 71 that connects to the guide rod 72 passes through the limiting frames 61.

[0048] like Figure 1 As shown, a support roller 73 is installed on the top of the V-shaped rod 71, and the support roller 73 can abut against the inner wall of the pipe.

[0049] When using, such as Figure 2 and Figure 3 As shown, rotating the adjusting cylinder 41 causes the threaded disc 4 to rotate synchronously, causing the threaded slider 42 to drive the blade 43 to move radially along the threaded disc 4. Simultaneously, since the adjusting cylinder 41 and the threaded cylinder 9 are connected by a thread, and the threaded cylinder 9 and the rotating shaft 3 are slidably connected, the rotating shaft 3 remains stationary. As the adjusting cylinder 41 rotates, it drives the threaded cylinder 9 and the cone 8 to move axially along the rotating shaft 3. Because the V-shaped rod 71, the cone 8, and the support frame 6 are all slidably connected, the cone 8 pushes the V-shaped rod 71 to move radially along the rotating shaft 3, causing the support roller 73 to abut against the inner wall of the pipe, thus enabling the support roller 73 to support pipes of different inner diameters. Since the blade 43 can drive the bristles 45 to move radially along the threaded disc 4, it can also clean pipes of different inner diameters.

[0050] like Figure 2 and Figure 3As shown, after adjusting the positions of the support roller 73 and the brush bristles 45, tighten the locking bolt 46 to lock the adjusting cylinder 41 and the rotating shaft 3. External driving force drives the housing 1 along the inside of the pipe. The drive motor 2 drives the rotating shaft 3 to rotate, which in turn drives the adjusting cylinder 41, the threaded disc 4, the blades 43, and the brush bristles 45 to rotate. The brush bristles 45 clean the inner wall of the pipe, and the blades 43 blow away the dust. Simultaneously, the rotating shaft 3 drives the threaded cylinder 9, the cone 8, the moving frame 7, and the support roller 73 to rotate.

[0051] like Figure 1 and Figure 6 As shown, after the pipe cleaning is completed, the cleaning device is removed from the pipe, and the adjusting cylinder 41 is rotated in the opposite direction. Under the action of the return spring 63, the V-shaped rod 71 is reset.

[0052] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0053] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
